terminal junkie n. [UK] A {wannabee} or early {larval stage} hacker who
   spends most of his or her time wandering the directory tree and writing
   {noddy} programs just to get a fix of computer time. Variants include
   `terminal jockey', `console junkie', and {console jockey}. The term
   `console jockey' seems to imply more expertise than the other three
   (possibly because of the exalted status of the {{console}} relative to
   an ordinary terminal). See also {twink}, {read-only user}.
   Appropriately, this term was used in the works of William S. Burroughs
   to describe a heroin addict with an unlimited supply.
